When the bases are the same, you can combine the exponents.

x³   [x is where the base is]

For example:

x³ · y² = x³y²   You can't simplify this anymore because they have different bases/variables

[when you multiply a variable with an exponent by a variable with an exponent, you add the exponents together] so:

x² · x³ = x^{2+3}=x^5

[when you multiply a variable with an exponent by an exponent, you multiply the exponents together] so:

(x³)²=x^{3*2}=x^6

-2y^2*xy^4=-2x(y^{2+4})=-2xy^6

Probability can be calculated using the formula
AveGali [126]
It really depends on the situation as probability depends on logic more than simple mathematical equations. However you must keep in mind a few principles:
1- P = number of possible outcomes of the event / total outcomes
2- P always less than or equal to 1.
3- For independent events A and B to occur simultaneously, P= P(A) x P(B)
